__END__ =head1 NAME SNMP::Info::Layer2::C2900 - SNMP Interface to Cisco Catalyst 2900 Switches running IOS =head1 AUTHOR Max Baker =head1 SYNOPSIS # Let SNMP::Info determine the correct subclass for you. my $c2900 = new SNMP::Info( AutoSpecify => 1, Debug => 1, # These arguments are passed directly to SNMP::Session DestHost => 'myswitch', Community => 'public', Version => 2 ) or die "Can't connect to DestHost.\n"; my $class = $c2900->class(); print "SNMP::Info determined this device to fall under subclass : $class\n"; =head1 DESCRIPTION Provides abstraction to the configuration information obtainable from a C2900 device through SNMP. For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above. my $c2900 = new SNMP::Info::Layer2::C2900(...); =head2 Inherited Classes =over =item SNMP::Info::CiscoVTP =item SNMP::Info::CDP =item SNMP::Info::CiscoStats =item SNMP::Info::CiscoConfig =item SNMP::Info::Layer2 =back =head2 Required MIBs =over =item CISCO-C2900-MIB Part of the v2 MIBs from Cisco. =back =head2 Inherited MIBs See L for its MIB requirements.

On the 2900 devices i_name isn't reliable, so we override to just the description. Next all dots are changed for forward slashes so that the physical port name is the same as the broadcasted CDP port name. (Ethernet0.1 -> Ethernet0/1) Also, any weird characters are removed, as I saw a few pop up. =item $c2900->i_duplex() Returns reference to map of IIDs to current link duplex Crosses $c2900->c2900_p_index() with $c2900->c2900_p_duplex() =item $c2900->i_duplex_admin() Returns reference to hash of IIDs to admin duplex setting Crosses $c2900->c2900_p_index() with $c2900->c2900_p_duplex_admin() =back =head2 C2900-MIB Port Entry Table =over =item $c2900->c2900_p_index() Maps the Switch Port Table to the IID (B) =item $c2900->c2900_p_duplex() Gives Port Duplex Info (B) =item $c2900->c2900_p_duplex_admin() Gives admin setting for Duplex Info (B) =item $c2900->c2900_p_speed_admin() Gives Admin speed of port (B) =back =head2 Table Methods imported from SNMP::Info::CiscoVTP See L for details. =head2 Table Methods imported from SNMP::Info::CDP See L for details. =head2 Table Methods imported from SNMP::Info::CiscoStats See L for details. =head2 Table Methods imported from SNMP::Info::CiscoConfig See L for details. =head2 Table Methods imported from SNMP::Info::Layer2 See L for details. =head1 SET METHODS These are methods that provide SNMP set functionality for overridden methods or provide a simpler interface to complex set operations.
